The KWA M11A1 NS2 model is a great addition to KWA's revolutionary NS2 gas blow back system. This is the M11A1 gas blow back SMG that features an astonishing rate of fire. The M11A1 is a great all around gas blow back because it is reliable, accurate, realistic, it has a great feel and sound to it when firing. The M11A1 is reliable because it is built by the same company that manufactures the nearly indestructible M-Series pistols, with the same kind of quality in mind. Similar to its real counterpart, the M11A1 fires from a true open bolt system. A sliding stock can extend out allowing users to remain stable while firing the weapon. Small and compact, the M11A1 provides users with a nimble light weapon with an extremely high rate of fire.

An incredibly compact weapon, this is closer to a machine pistol then it is a submachine gun. Around 1300 gr and approximately 250 mm, this thing occupies as much space and mass as a large pistol but with the enlogated magazine it pulls its center of mass central and low making it handle very cleanly with the ability to naturally turn around its center point quickly. The 230 mm extendible stock is a bit tight for bigger operators but for most it functions as a better-then-nothing short stock. Although not strictly necessary, the frame stock combined with the forward sling loop offer a solid support for keeping that full auto fire on target.

This model features the System 7 gas system which is both reliable and consistent as well as featuring enough robustness to tolerate wear and tear over time very well. The weapon is also all-metal so unlike other polymer models this one not only feels more realistic but it generally feels and sits better in terms of mass and rigidity.

Speaking of fire, this M11 keeps the groups pretty tight; on full auto, things open up a bit with is 20 BBs per second rate of fire which can empty the entire 48 round magazine in less than 3 seconds. Consequently, controlled bursts of 2-3 rounds is entirely manageable with short trigger taps which helps keep your fire controllable but still high threat against your targets. Despite its controllability, its high cyclical rate means that even short bursts sound like small chainsaws exploding which does a good job of spooking the enemy. The outer barrel is threaded for a M11A1 Ingram spesific dummy silencer.

In the heart of the new M11A1 SMG is a brand new lightweight alloy bolt featuring the NS2 gas system with a redesigned composite jet nozzle for improved performance and durability. The hop-up unit has also been redesigned to incorporate a integrated feed ramp for positive feeding during continuous full-auto operations. Another new feature is the addition of the impact block reset to increase cyclic rate and improve overall reliability. New M11A1 magazines now feature reinforced feed lips and silent fill valves. Taking full advantage of the NS2 design, the new M11A1 fires at an average of 350 FPS with an impressive ROF of 25 to 28 rounds per second.
